The tests indicate Sidney Crosby doesn't have a concussion. Crosby's body isn't so sure.
The Pittsburgh Penguins star said Monday he's dealing with a recurrence of concussion-like symptoms and is out indefinitely.
Crosby, who missed more than 10 months after taking shots to the head in successive games in January, hasn't played since developing a headache following a 3-1 loss to Boston last week.
"I ended up skating the following day after with a little bit exertion and it just didn't feel right," he said. "After kind of talking with everyone it was better to be cautious here and not take any chances."
The 24-year-old passed an ImPACT test - designed to diagnose concussions - last Wednesday.
